COURAGE sits in the hippocampus

COURAGE sits in the hippocampus

 Fear is in the amygdala but courage in the hippocampus, conclude this work from the University of Uppsala (Sweden), presented in the journal Nature Communications and which identifies specifically reckless cells in this area of ​​the brain. These "OLM" cells, which are very sensitive to nicotine, further contribute to explaining why people smoke when they are anxious.


The OLM cells or "oriens-lacunosum moleculare" interneurons present in the hippocampus could thus explain the bravery of certain people who will experience pleasure in performing dangerous or exhilarating acts. Even within siblings, the researchers point out, there are considerable differences in risk taking. Until this work, the neural mechanisms behind these risky behaviors remained poorly understood. These neuroscientists identify, for the first time, the key role played by certain cells of the hippocampus in risk taking and anxiety.

These OLM cells


 when stimulated, induce a specific cerebral rhythm in the animal, when it feels safe in a threatening environment. Manipulation of these OLM cells also helps to control anxiety and risky behaviors. It is therefore a step towards a therapy that makes it possible to quickly control the propensity to take risks but above all to treat pathological anxiety, the two traits being generally linked.

Targeting OLMs to Reduce Anxiety:


 Adaptive anxiety is certainly essential for survival, but dysfunctional and chronic, it significantly impairs well-being and quality of life. Patients with anxiety disorders are frequently prescribed antidepressants that work throughout the brain, not just key areas, with side effects that can be severe. Thus, being able to target a specific area of ​​the brain or even this very specific group of cells to control anxiety is a major advance in the treatment of anxiety and associated disorders such as depression.

Targeting OLMs with pharmacological agents:


 The same team of scientists had discovered, in previous research, that OLM cells were the "guardians" of memory in the hippocampus and that these cells were very sensitive to nicotine. A finding that, in light of the latest results, may explain why people smoke when they are anxious, says Dr. Richardson Leao, a researcher at the Brain Institute of the Federal University of Rio Grande do Norte.

We know better the role of the hippocampus in memory and cognition than in emotions. It is only in recent years that scientists have begun to appreciate the role of the hippocampus in regulating emotions.

However, the discovery of these neurons and their role in anxiety and risk-taking could pave the way for the development of more effective anxiolytics and antidepressants with fewer side effects.

Is the hippocampus used for emotion?

The hippocampus is a key brain region in the emotional brain network and plays a significant role in social cognition and emotion processing in the brain.

What emotion is associated with the hippocampus?

Just as the amygdala is involved in implicit emotional memory, the hippocampus is involved in explicit memory about emotional situations ( Figure 1). Thus, when emotionally aroused we form semantic and episodic memories about such situations.

Why is courage called strength?

The ideal in courage is not just a rigid control of fear, nor is it a denial of the emotion.

What part of the brain controls confidence?

medial prefrontal cortex

Beer et al. (2010) demonstrate that medial prefrontal cortex and orbitofrontal cortex are related to self-evaluation. In addition, researchers find out that self-esteem can be traced back to specific cerebral regions that involve emotional coping strategies, such as threaten, stress, anxiety, and fear.

Is courage inherited or learned?

Though courage is often thought of as an inborn character trait, it's actually a way of being and a practice that can be learned for coping with difficulty. In other words, courage can become a habit. Usually, we think of habits as actions, like brushing your teeth or exercising.

What are the 4 types of courage?

Conclusion. Everyday courage, including moral, intellectual, disciplined, and empathetic courage, requires explicit practice and discipline.

Does the hippocampus control fear?

Many studies have demonstrated that the hippocampus is a fundamental structure supporting adult fear conditioning, especially contextual fear learning (O'Keefe and Nadel, 1978; Eichenbaum, 1996; Fanselow, 2000; LeDoux, 2000; Otto et al., 2000; Anagnostaras et a., 2001; Otto and Giardino, 2001; Debiec et al., 2002; Rudy ...

Being an integral part of the limbic system, hippocampus plays a vital role in regulating learning, memory encoding, memory consolidation, and spatial navigation.

What does the hippocampus do when scared?

The hippocampus is the brain's memory center. If it determines that the current fear stimulus is a threat but not life-threatening, the hippocampus heightens your senses to an almost superhuman degree and triggers your fight-or-flight response.
